Due to the … WebA screening matrix provided in this guidance ( Table 6-2) helps the user select remedial technologies based on the characteristics of the fractured rock at a site. Once potential remedial technologies are identified, multiple alternatives can be developed to address contamination at fractured rock sites. Figure 6-1.
Webmetamorphic rocks), when not fractured, typically have very low porosity. A or as part of weathering (e.g. related to pressure release). Strong rocks, like granite or gneiss, may not fracture as easily as weaker rocks, but they can still be sufficiently well broken up to induce significant fracture-related porosity – especially near to surface. WebOct 1, 2024 · Abstract. The deeply fractured rock mass exists in the environment of in-situ stress and high seepage pressure, and they are prone to seepage-slipping failure. Therefore, it is of excellent engineering value and theoretical significance to study the nonlinear seepage evolution of fractured rock mass under water-rock mass coupling.
